How to raise baby giant salamander? Can the turtle eat the feed? Come in and say,

The so-called frog fish outside is an oriental salamander, not a real giant salamander.

Oriental salamanders can be kept in fish tanks, and they should see the sun often, but not too much. It likes to eat live food, such as water worms and red worms.

How to feed

Newts can be kept in large glass fish tanks, which is convenient for observing their activities. The bottom of the tank is paved with some washed sand and gravel, and 30 cm deep pool water or well water is injected, and a small amount of aquatic plants such as Ceratophyllum are added to decorate an ecological environment similar to the capture area. Gravel has the function of adsorbing dirt; Aquatic plants can carry out photosynthesis, increase the oxygen content in water and provide eggs for salamanders.

Clean pool water is better to feed, and well water is also suitable. If tap water is used, it can only be used after 3-5 days, otherwise the chlorine in tap water will lead to the death of salamanders. Changing water is a routine management work. Keeping the water fresh and clean is beneficial to the normal life of salamanders. Change water every 2-3 weeks in winter and every 3-5 days in other seasons.

Newts like to eat live animals. Water earthworm is an ideal feed, just put a little every other day; Earthworms can also be wrapped in a single layer of gauze and hung in water with a rope. Earthworms will stretch out part of their bodies through the gaps in the gauze, and salamanders will swim to pull food. In addition, there are tadpoles, dragonflies, water fleas and so on. It is also the favorite food of salamanders. In the absence of small animals, lean pork can also be cut into small pieces for feeding. But be careful not to eat too much, and it is advisable to have no leftovers to prevent food from rotting and affecting water quality.

How to breed

Newts living in nature lay eggs in March-April, most of which are in May. Because the room temperature of the oriental salamander reared indoors is often higher than the natural temperature, the spawning period should be about one month in advance. From February to March, when the average temperature is above 10℃, the paunchy female salamander begins to lay eggs, reaching the peak in April, and then gradually decreasing.

Amphibians are generally fertilized in vitro, and salamanders are special. They are fertilized in the body. Before ejaculation, the male salamander swims around the back of the female salamander, touches the cloacal hole of the female salamander with his nose and mouth, and his tail bends forward and shakes rapidly. After successful courtship, the female salamander walked with the male salamander, and the male salamander immediately discharged the milky bag and quickly sank to the bottom of the water. At this time, the female salamander touches the front end of the seminal vesicle with the reproductive cavity, and slowly sucks the sperm in the seminal vesicle and stores it in the fallopian tube. After that, sperm and eggs will be fertilized in the fallopian tube.

It is very interesting for female salamanders to lay eggs. First, they choose the leaves of aquatic plants in the water, and then clamp the leaves together with their hind legs, and repeat several times. Finally, they roll the flat leaves into folds and wrap them around the cloacal foramen, and let them stand for 3-5 minutes, and the fertilized eggs are produced and wrapped in the leaves. After laying eggs, the female salamander lies to the bottom of the water, takes a rest and then floats up to continue laying eggs, usually laying only one egg at a time.

A fertilized egg is the starting point of a new life. Under the suitable conditions of water, oxygen and temperature, fertilized eggs divide regularly for many times and become tadpoles. After 2-3 days, tadpoles first grow a pair of forelimbs, and then grow hind limbs. After 3-4 months, the larvae developed into salamanders.

observe carefully

First, observe the external shape of the salamander, which consists of five parts: head, neck, trunk, limbs and tail. Adults are 6-8 cm long. The skin is bare, the back is black or gray-black, there are slightly prominent moles on the skin and irregular orange-red spots on the abdomen.

Newt neck is not obvious, trunk is flat, limbs are developed, forelimbs have four fingers, hind limbs have five toes, there is no web between fingers (toes), and tail side is flat and long. Newts crawl on all fours under water and on land, and swim by bending and swinging their trunks and tails up and down in the water.

Male and female differences of salamanders;

Males are slightly smaller than females; Males are lively and sensitive, females have a big abdomen and are slow to move; The male cloacal foramen is convex, especially in the breeding season, with long cracks and obvious villous papillae, even protruding outward, while the female cloacal foramen is flat, with short cracks and no obvious papillae.

In the process of raising salamander, it will be found that it has molting phenomenon. Please note that salamanders shed the skin on the top of their heads first, and then shed their trunks, limbs and tails. The skin shed by the newt is sometimes swallowed by itself and sometimes eaten by its companions.
